Zusammenfassung, Abstract
Conservation tillage systems have several advantages. The positive effects concerning the reduction of soil erosion are well known and documented. The more residues are left on the soil surface the higher reduction of soil erosion is achieved. At the same time thick mulch layers have negative effects on the emergence rate of the followed crop. Modern machinery for conservation tillage improved the incorporation of crop residues in the last years which effects the residue cover after tillage. Especially at deep working depth (above 13 cm) the benchmark of 30% residues cover can't be achieved any more. In a three years project the relationship of emergence rate from straw quantity, working depth and residue cover is investigated.
